Abstract
In this study, we enhanced the flexural strength of cordierite ceramics by incorporating h-BN (hexagonal boron nitride) nanoparticles, facilitated by the slip casting process. Initially, commercial cordierite powder with an average particle size of 10 mm underwent a ball-milling process to reduce the size to 2.5 mm and simultaneously achieve.....

Abstract
Sodium silicate solutions are used as an eco-friendly binder in the casting process. However, the strength of sand molds using the sodium silicate solutions is reduced because of their low humidity resistance. In this study, silica nanoparticles were added to a sodium silicate solution with a constant SiO

Abstract
CBAPC (chemically bonded aluminum phosphate ceramic) binders have various advantages, including superior corrosion resistance and strength at high temperature. They are also a non-toxic and eco-friendly material. We investigated an inorganic binder based on CBAPC using artificial sand for casting. The CBAPC binders were synthesized with various P/Al molar ratios.....
